Loading vulnerability…
CVE-2021-45901 is an information disclosure issue in the ServiceNow Now Platform Orlando release affecting the password-reset form. The password reset workflow returns different responses for invalid authentication attempts depending on whether the supplied username exists. This discrepancy allows an attacker to distinguish valid from invalid usernames through the public password reset interface, resulting in username enumeration.

This repository provides a proof-of-concept exploit for CVE-2021-45901, a username enumeration vulnerability in ServiceNow Orlando (glide-orlando-12-11-2019__patch5-06-17-2020). The main exploit is implemented in 'enumSNOWUsers.py', a Python script that automates the process of sending crafted HTTP requests to the ServiceNow password reset endpoint. By analyzing differences in the HTTP response (specifically, the XML 'answer' field in the response body), the script determines whether a given username is valid or not. The script requires a list of usernames (users.txt), and valid session tokens (JSESSIONID, CSRF token, X-UserToken), which can be obtained from client-side code. The exploit is unauthenticated but does require access to the password reset form and the ability to retrieve session tokens. The repository also includes a detailed README.md explaining the vulnerability, exploitation steps, and remediation advice. No weaponized or post-exploitation payloads are present; the exploit is strictly for username enumeration (POC).
